Typing of hepatitis C virus (HCV) isolates from Argentine patients was performed by using different methodologies in a population of 243 patients. HCV subtype was assigned based upon restriction fragment length polymorphism (RFLP). HCV RNA genomes obtained from serum samples were classified as belonging to clade 1 (53.5%), 2 (23. 0%), or 3 (8.6%); 14.8% of samples showed HCV mixed infections, more frequently implying different subtypes within the same clade. In addition to RFLP typing, phylogenetic relatedness among sequences from both 5' untranslated region (n = 50) and nonstructural 5B coding region (n = 15) was established.

Background: Human hepatitis is an inflammation of the liver brought on by the DNA virus known as the hepatitis B virus (HBV). Around the world, 240 million people are thought to have HBV in a chronic state. The prevalence of viral hepatitis is extremely high in Africa.

Hepatocellular carcinoma (HCC) is one of the most prevalent malignant tumors, often with a poor prognosis. The HBx protein, encoded by the hepatitis B virus (HBv), is significantly associated with the pathogenesis of HCC. Although studies suggested that the von Willebrand factor (vWF) is key to the progression of HCC associated with HBv, the underlying mechanisms are largely obscure.

Hepatitis B virus (HBV) X protein (HBx) is a key factor for regulating viral transcription and replication. We recently characterized homeobox protein MSX-1 (MSX1) as a host restriction factor that inhibits HBV gene expression and genome replication by directly binding to HBV enhancer II/core promoter (EnII/Cp) and suppressing its promoter and enhancer activities. Notably, HBx expression was observed to be repressed more drastically by MSX1 compared to other viral antigens.

Hepatitis B virus (HBV) infection is a major global health concern, with liver transplantation (LT) serving as a critical treatment for end-stage liver disease caused by HBV. However, the risk of HBV reinfection after LT remains significant, necessitating effective prophylaxis. Today, the combination of hepatitis B immune globulin (HBIG) and high-barrier nucleos(t)ide analogues (NUCs) is the standard of care for preventing HBV recurrence post-LT but concerns about the cost of HBIG and access to high-barrier NUCs have led to a reduction in the use, dose, and duration of HBIG in recent years.
